Well, I definitely got my hands wet with running Windows PowerShell scripts today. I ran into a number of issues in the process, so I better make note of the solutions for next time around.
First off, PowerShell is Windows' task automation framework. Good for running scripts on windows machines. As far as I can tell, you can run PowerShell in the command prompt with the command call PowerShell.exe: C:\Scripts>PowerShell.exe. Or, you can open the Start Menu and start typing PowerShell and open Windows PowerShell.

Now, you have a script and want to run it right? Pretty easy right? Not for me. I had to jump through some serious hoops here... so I tried typing Suspend.ps1. No dice. I'd get an error saying the command isn't recognized. Through some bing magic I found that you need to include the complete file path: C:\Scripts\Suspend.ps1

Or, if you are currently in the specified folder you can use the .\ notation: .\Suspend.ps1

It's better to use the full notation, to prevent it from finding a file of the same name in your current Windows path (it looks through the entire path, not just your current directory). FYI - you can see your current path with this command:
$a = $env:path; $a.Split(";")

Anyways, once I figured out how to actually make the call from the command prompt, I kept getting this weird signing error:
File C:\Scripts\Suspend.ps1 cannot be loaded because the execution of scripts is disabled on this system. Please see "get- help about_signing" for more details. At line:1 char:19 + C:\Scripts\Suspend.ps1 <<<<
This is where it got tricky. I searched around for a bit and found that by default, windows machines are set to restrict you from running scripts. To see your execution policy try using the command Get-ExecutionPolicy. If you've never messed with this before, it'll probably say Restricted, like mine did. Now, the simple fix to change this is to use the following command call: Set-ExecutionPolicy RemoteSigned. If this works for you, congratulations! You're good to good. For me... it didn't. I got some weird error that looked like the following:
Set-ExecutionPolicy : Access to the registry key ‘HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1\ShellIds\Microsoft.PowerShell’ is denied. At line:1 char:20 + Set-ExecutionPolicy <<<< RemoteSigned
Is this familiar to you? Hopefully not, but it if is. There's a solution.

To fix this and add the RemoteSigned execution policy by hand you'll need to work a little Windows registry magic.

Open registry by opening the start menu and typing regedit into the search box
